MACHlNE FOR CUTTING WINDOW-SHADES.

SPECIFICATION forming part of Letters Patent No. 592,495, dated October 26, 1897.

Application filed January 14, 1897. Serial No. 619,164. (No model.)

To al?, whom, it may concern:

Be it known that I, EDWARD OswALD, a citizen of the United States, and a resident of Johnstown, in the county of Cambria and State of Pennsylvania, have made certain new and useful Improvements in Machines for Cutting lVindowShades, of which the following is a specification.

My invention is an improvement in machines for cutting window-shades to any desired width, and is useful in the factory as well as in the hands of shopkeepers vending such goods.

The object of the invention is toprovide for putting shades in position in houses where there are windows varying in size, and its em ployment saves time, labor, and expense in that shades on rollers of one size, prepared at the factory, may be taken to the house to be equipped and by the use of my improved Inachine applied more quickly than is the case where measurement is first made and separate shades provided at the manufactory for each separate window.

I provide a frame or table and fix thereon transversely a scale graduated in fractions of an inch,preferably three or four feet in length. In close proximity and parallel thereto is fixed a metal strip to form a track for two sliding holding devices forming bearings to receive the pivot-like projections located upon or attached to the ends of a shade-roller. These sliding bearingpieces have slotted holes, through which screws are passed to clamp said bearing-pieces in position on the track at variable points along the scale. I provide a knife or cutter and means for attaching it adj ustably at any point along the length of the scale.

The accompanying drawings illustrate my invention.

Figure l is a plan view of my improved machine for cutting window-shades. Fig. 2 is a side view or elevation of the machine, and Fig. 3 is an end view.

F is a frame or table made of a board onehalf inch thick, twelve inches wide, and three or four feet long, with end pieces or supports N.

S is a scale graduated in fractions of an inch,.fixed to one edge of the frame or table.

In close proximity to the scale S and parallel` thereto is fixed a metal strip M, which forms a track for two sliding holding devices h, forming bearings to receive the pivot-like projections located upon or attached to the ends of the shade-roller. These holding devices are straps of metal bent at right angles, the vertical portion being perforated or perforated and slotted, as shown in Fig. 3. The horizontal limb of the holding device is slotted to receive a set-screw and the terminal is bifurcated, and its dependent projections .c engage opposite sides of the track M and retain the holders 7L` against any tendency to rotate when the nut t of the set-screw is turned.

On the front edge of the frame belowthe scale there is fixed a bar or track B. It is supported a slight distance from the edge ofthe board upon blocks 0c, so as to have a' slight space between said track and the edge of the frame or table. Upon this track I place a knife or cutter 7a, provided with a set-screw m,

which operates to clamp the forked end of the knife at any desired position upon the trackB.

Upon the back of the frame or table is a trough T, preferably about two inches square, within which the roller may be placed and cut to a length substantially equal to the width of the shade or curtain.

The operation of the apparatus is as follows: In use projections upon the end of the shaderoller are placed in the holes or slots s in the holding devices 7L and the shade is firmly held in position. The knife or cutter is then slipped along the bar B to the division on the scale indicating the width which it is desired to cut the shade and fastened in such position by means of the thumb-screw m. The shade is then pulled along the knife until entirely unwound from the roller, when it and the strip cut therefrom are removed. The roller is then placed in trough T and sawed to any length required for the support of the shade.

My improved machine is designed to be s0 compact and light that it may be carried by the Workman to the place to be equipped with shades, and the time, labor, and expense otherwise incurred in measuring and fitting IOO ' zontal surface xed together at a right angle,

in a lower plane and a cutting edge adjust- Io ably supported on the last-named rail below the projecting edge of the horizontal surface, substantially as described.

EDWARD osWALD.
